This is a Marshall basketweave 1960B cabinet from 1971 with nine-inch logo ... with a 1967 JMP 50W plexi sitting on top. The early seventies were a transition year from basketweave to checkerboard (left portion of picture) grill cloth, and with Celestion being bought by Rola. Nothing quite sounds like an old 4X12. |
|
Cabinet rear view. The '67 JMP is a tube rectified version. |
|
Original input cup and tags. |
|
Rear panel is particle board instead of plywood. Something Marshall switched to during 1971. |
|
Center post is 2X4 versus a 2X2 in later cabinets. Speakers are 16 ohm pre-Rola greenback 25W Celestions dating to January 1971. Three have Pulsonic 003 cones one is a probably a recone with 444 cone. |
|
T1221 frames and 75Hz resonance. |
|
The twins ... sure can raise a little heck with this setup. On left is a 1967 blackflag plexi JTM50 sitting on top of a 1960AX cab with Weber Silver Bells and 1230-55's. |
